To all whom 'it may concern.-

Be it known that I, PETRUS SANDER, a citizen of Sweden, residing atMoline, in the county of Rock Island and State of Illinois, haveyinvented certain new and useful Improvements in Apparatus for Actuating11V ater-Wlotors, of which the following is a specification.

This invention relates to improvements in apparatus for actuating watermotors and more particularly to that class of water motors designed forintermittent motion wherein the motive power is the rising tide of thesea.

Myapparatus consists of three floats each occupying a separate chamber.Two of the chambers are in communication with the sea at such a depth asto be nearly but not entirely submerged at high tide and ithe third ispositioned entirely above the water line.

The object of the invention is to produce a device of this class that ischeap to manufacture and that is easy to construct.

With the foregoing and other objects in View the invention consists inthe combination and arrangement of parts to be hereina-fter fullydescribed in the following specification, pointed out in the claim andillustrated in the accompanying drawings which form a part of thespecification and in which- Figure 1 is a `vertical sectional sideelevation of the device. Fig. 2 is a plan.

Like reference characters indicate corresponding parts throughout theseveral views. I

1, 2 and 3 representthe chambers and 4, 5 and 6 the floats. structedwithout any side or end walls but with grooved rods for supports whichsustain the roof 7 The float 4 disposed within this chamber is providedat its four corners with rollers Briding in the grooved rods orsupports. Tot-he fioat 4 is secured a rack 9 which extends through theroof 7 and is partially supported by a guide 10 disposed upon,the roofand meshes with a serrated wheel 11 that is mounted upon a shaft 12journaled in a pair of supports 13 also disposed upon the said roof. 14is a sprocket wheel also carried by the shaft I12 and connected byy achain 15 to another sprocket wheel 16 mounted upon a shaft 17 that isjournaled in supports 18 upon the roof 19 of the chamber 2. This chamberis The chamber 1 is con-v walled and preferably formed of masonry ormetal of some kind. The chamber 2 is further provided with an arm 20which is hol-low and communicates with the interior .and projects outfrom the said chamber and has as a covering over its `free extremityrThis chamber is further provided with a substantially cylindricallhollow water tight inner compartmentv 22 which snugly incases the float5 and is provided lnear its lowervtermination with a water inlet valve23 that communicates with the contents of the chamber 2 and at its upperextremity with an air pipe 24 and with an outlet pipe 25 near its basewhich pipe leads up through the chamber 2 and into thechamber 3 .and isprovided with a check valve 26 toprevent the return of the water The oat5 is Aprovided with a rack 27 that extends up through the roof 19 andthrough a guide 28, which is secured to the said roof, and engages aserrated, wheel 2S) mounted upon the shaft 17. I

Referring now to the chamber 3 which is disposed above the water levelthe same is provided with the float 6 and with an outlet pipe 30 vofmuch smaller diameter than the pipe 25 that furnishes water to the saidchamber; the pipe 30 is provided with a turbine nozzle 31 above a waterwheel 32 which is actuated by the water coming from the said nozzle andthrough thel medium of the water wheel 32 power may be conveyed ortransmitted as desired by any preferred form of power transmissionapparatus.

Operation: The chamber 1 is seated in shallow water at such a pointAthat the high tide will not reach its roof; the chamber 2 is similarlyseatetbbut the open end of its.

arm 20 is so positioned as to be below thel level of the water athightide. After the device Ais installed in position the first high tideyencountered by it will raise the float 4 but as the chamber 2 will bevoid of water no power will be generated, the first tide being used tofill the chamber 2 through the medium of its arm 20. After the tide hasreceded and the float 4 has been borne upon it to a vpoint nearest thebase line of the chamber 1 the device will be in readiness for usefuloperation. The tide now again coming in will raise the float 4 whichwill raise the rack 9` and so rotate the shaft 12 transmitting power bythe chain 15 to the shaft- 17 the connections of which will depress therack 27 (the water level now being below the open end ot' arm 20) andfloat 5 will force the water in the compartment 22 out through the pipe25 up into the chamber 3. Part of this Water Will escape with greatforce through the pipe and nozzle 31 upon the Water Wheel 82 While theexcess Water Will lill the chamber 3 thus raising the float 6; when thetide has reached its greatest 'height the Water Within the compartment22 Will have been forced out, the chamber' 2 will beginagain to fillwith water coming in through the arm 20 and valve 23 thus raising thefloat 5 and rack QT, the air pipe 24 permitting the operation, andWhatever Water now remains in the chamber 3 Will soon be evacuated. Withthe receding tide the oat 4f. will again be carried to its lowestlevel,l during' which process the vpower is stopped, when it will beready for the returning tide Which will cause a resumption of power.

What is claimed is -In a device of the class described, the combinationwith a pair of partially submerged Water chambers, of a third Waterchamber disposed above the Water level, a float Within one of thepartially submerged water chambers, an intermittently submerged armopen'at either end wconnected to the other partially submerged Waterchamber, a compartment having an inletI valve disposed 'Within the lastnamed partially submerged chamber, an air pipe connected to the saidinner compartment projecting above the high Water level, a float withinthe said inner compartment, power transmission mechanism connecting theklast named float and the float beforementioned; an outlet pipe providedwith a check valve connect-ing the said inner compartment and the aforelsaid third Water chamber, a float Wit-hin the last named chamber, anoutlet pipe for that chamber and a Water wheel disposed beneath' thesaid outlet pipe.

In testimony that I claim the foregoing' as my own I have heretoaftixedmy signature inthe presence of two subscribing witnesses.
